Multiple file upload in php

Question

I want to upload multiple files and store them in a folder and get the path and store it in the database... Any good example you looked for doing multiple file upload...

Answer 1

I run foreach loop with error element, look like

 foreach($_FILES['userfile']['error'] as $k=>$v)
 {
    $uploadfile = 'uploads/'. basename($_FILES['userfile']['name'][$k]);
    if (move_uploaded_file($_FILES['userfile']['tmp_name'][$k], $uploadfile)) 
    {
        echo "File : ", $_FILES['userfile']['name'][$k] ," is valid, and was                      successfully uploaded.\n";
    }

    else 
    {
        echo "Possible file : ", $_FILES['userfile']['name'][$k], " upload attack!\n";
    }   

 }

<?php
if (isset($_POST['submit'])) {
    $j = 0; //Variable for indexing uploaded image 

 $target_path = "uploads/"; //Declaring Path for uploaded images
    for ($i = 0; $i < count($_FILES['file']['name']); $i++) {//loop to get individual element from the array

        $validextensions = array("jpeg", "jpg", "png");  //Extensions which are allowed
        $ext = explode('.', basename($_FILES['file']['name'][$i]));//explode file name from dot(.) 
        $file_extension = end($ext); //store extensions in the variable

  $target_path = $target_path . md5(uniqid()) . "." . $ext[count($ext) - 1];//set the target path with a new name of image
        $j = $j + 1;//increment the number of uploaded images according to the files in array       

   if (($_FILES["file"]["size"][$i] < 100000) //Approx. 100kb files can be uploaded.
                && in_array($file_extension, $validextensions)) {
            if (move_uploaded_file($_FILES['file']['tmp_name'][$i], $target_path)) {//if file moved to uploads folder
                echo $j. ').<span id="noerror">Image uploaded successfully!.</span><br/><br/>';
            } else {//if file was not moved.
                echo $j. ').<span id="error">please try again!.</span><br/><br/>';
            }
        } else {//if file size and file type was incorrect.
            echo $j. ').<span id="error">***Invalid file Size or Type***</span><br/><br/>';
        }
    }
}
?>

It's not that different from uploading one file - $_FILES is an array containing any and all uploaded files.

There's a chapter in the PHP manual: Uploading multiple files

If you want to enable multiple file uploads with easy selection on the user's end (selecting multiple files at once instead of filling in upload fields) take a look at SWFUpload. It works differently from a normal file upload form and requires Flash to work, though. SWFUpload was obsoleted along with Flash. Check the other, newer answers for the now-correct approach.

Here is a function I wrote which returns a more understandable $_FILES array.

function getMultiple_FILES() {
    $_FILE = array();
    foreach($_FILES as $name => $file) {
        foreach($file as $property => $keys) {
            foreach($keys as $key => $value) {
                $_FILE[$name][$key][$property] = $value;
            }
        }
    }
    return $_FILE;
}

Answer 5

Simple is that, just count the files array first, then in while loop you can easily do this like

$count = count($_FILES{'item_file']['name']);

now you got total number of files right.

In while loop do like this:

$i = 0;
while($i<$count)
{
    Upload one by one like we do normally
    $i++;
}

Answer 6

this simple script worked for me.

<?php

foreach($_FILES as $file){
  //echo $file['name']; 
  echo $file['tmp_name'].'</br>'; 
  move_uploaded_file($file['tmp_name'], "./uploads/".$file["name"]);
}

?>
